AFR195's So my plan was to go with a CC503 cam over this coming winter with a set of roller rockers, and a set of valvesprings. Anyway I get a call from a buddy telling me he is going with a LS6 motor in his LT1 Camaro. He tells me I can have his AFR 195's for a grand, these heads need nothing bolt on and go. I have been doing some reading a lot to be honest with these heads I am going to need to go with a LT4 intake, seeing that I have a 94 Z28. What is the best intake to use? Eldebrock, next thing is cam choice, I already have a stall, LT's, CAI, and a tune which I know I will need another when I install the heads. What about the CC306 cam they make good power don't they?

You should get one of the GM LT4 intakes from somebody, The Edelbrock manifold isn't better due to a smallish plenum. If you do a CC306, it is a pretty aggressive cam so make sure get your valve springs set up for it.

And oh yea, I also run a set of AFR195s. Love them. They can also have some amazing work done to them as they have tons of meat on them. Are they the sportsmans or the competitions?
Port your stock intake to match, and get a custom cam.
You can have a cam ground on more modern lobes that will make just about the same peak as the 306, but with more under the curve and better manners. There is not a big price difference between a spec'd custom cam and a shelf cam. Most porters like LE and AI also have "semi-custom" grinds that are on their shelf ready to go, but using more favorable specs for our engines then an old SBC grind from Summit.

With AFR heads the 195 and up heads are LT4 heads. And to the OP the 195 heads and the cc306 will require a lot of RPM IMO

I think they are the sportsman so if I port my stock intake they will work with the heads? because I really don't want to use a Eldebrock intake, I am going to email AFR, when I get the heads I am going to get their opinon on the intake and a cam choice. I have been doing a lot of research the few past days the more reading I do the more confused I get. Some people are saying you can use the stock intake, other people are saying you can't without porting and stay away from the Eldebrock LT4, what to do!!!

I have the 195 eliminator,s. And a ported stock intake on my 95 TA. Comp custom cam, I ran the xfi280 for bout a year then I went with a larger cam. There are some good articles written about these heads and they used the xfi 280 from comp cams made lots of torque also.

Thanks for the info I will look at the heads for the stamp, I am still paying off my buddy as soon as I do that I will have them. He tells me that they are the torque monsters, first I heard of them being called them. Once I get the heads I will be able to share and find out more info on them, I will be sure to type it here. Once again thanks for the advise..
Just be cautious in saying that them being AFRs is a great thing around here! There's a lot of guys here running stock casting heads and intakes (with work of course) that will put an *** whooping at the track on full aftermarket cars! I love my AFRs but know the stock castings can perform impressively too.
Be certain to ask here before putting this thing back together, lots of great knowledge here that can recommend better combinations of parts to maximize performance for the same or maybe even less money. Remember these things LOVE compression.

The LT4 intake has the same ports as the late trapezoidal shape SMALL LT1 ports, it just has more material above the port which can be needed to seal to a very tall port or leaves room for port matching to tall ports. Regardless of what literature says it is worth at least trying an LT1 intake it might just be fine or the sealing margin at the top of the port can be narrow. If you know someone with a TIG a little material can be added to the LT1 sealing flange and remachined which would likely be better than the Edelcrap stuff.

Yeah I plan to get a hold of AFR, and asking their advise on what cam, and intake to use. I was going to go with LE's heads but to send my heads from Eastern Canada, and back along with the work I would be looking at 3 grand or more. When these AFR's came up for sale that's why I grabbed them quick. Thank-you for all the advise I really appreciate it all.
I wouldn't trust anyone answering the phone at AFR for info on the intake or cam, guys have already given you better option to call why do you want to make a bad choice?

GIZMO posted this comparison pic of the LT1 and LT4 intakes years ago to help set the record straight on what it is and isn't.
Some quick googling says several guys have put LT1 intakes on those heads with no trouble.
